<h1>Description</h1>
<p>This test validates that the performance.mark() method is working properly. This test creates the
following marks to test this method:
<ul>
<li>"mark1": created using a normal mark() call</li>
<li>"mark1": duplicate of the first mark, used to confirm names can be re-used</li>
</ul>
After creating each mark, the existence of these marks is validated by calling
performance.getEntriesByName() (both with and without the entryType parameter provided),
performance.getEntriesByType(), and performance.getEntries()
